Setting this option to false does not count missing bytes in files towards the
extraction limits, and allows to extract data up to the desired limit,
even when partial files are written.
When missing bytes are encountered, files are now written as sparse
files.
Using this option requires the underlying storage and utilities to support
sparse files.

When http_reply events are received before http_request events, either
through faking traffic or possible re-ordering, it is possible to trigger
unbounded state growth due to later http_requests never being matched
again with responses.
Prevent this by synchronizing request/response counters when late
requests come in.
Also forcefully flush pending requests when http_replies are never
observed either due to the analyzer having been disabled or because
half-duplex traffic.

This works around the new semantics of is_orig=T for "connections"
from DHCP servers to broadcast addresses. IMO, having the server address
as originator in the conn.log is still more intuitive.
The input framework currently gives a rather opaque error message when
encountering a line in which a required value is not provided. This
change updates this behavior; the error message now provides the record
element (or the name or the index element) which was not set in the
input data, even though it is required to be set by the underlying Zeek
type.
This test triggered ubsan by putting a function with the wrong type
as a post-processor into the .shadow file. Don't do that.
Likely Zeek should provide a better error message, but hand-crafting
.shadow files isn't what is normally done and this is to fix the
master build for now.
* topic/awelzel/3112-log-suffix-left-over-log-rotation:
cluster/logger: Fix leftover-log-rotation in multi-logger setups
cluster/logger: Fix global var reference
Populating log_metadata during zeek_init() is too late for the
leftover-log-rotation functionality, so do it at script parse time.
Also, prepend archiver_ to the log_metadata table and encoding function
due to being in the global namespace and to align with the
archiver_rotation_format_func. This hasn't been in a released
version yet, so fine to rename still.

This seems to have relied on the reading file twice behavior simply
testing that 16 lines are observed. Switch to using two separate
files and doing a system("mv ...") to trigger the REREAD logic, there's
not force_update() needed and it wouldn't do anything if the file
hadn't changed anyway.
Found while writing documentation and being confused why
all lines and end_of_data() arrive twice during startup.
The test is a bit fuzzy, but does fail reliably without
the changes to Raw.cc
Also fix not checking dev in the MODE_REREAD path.
Closes#3053
This commit adds support for the connection_id extension, adds a trace
that uses DTLS 1.3 connection IDs, and adds parsing for the DTLS 1.3
unified header, in case connection IDs are not used.
In case connection IDs are used, parsing of the DTLS 1.3 unified header
is skipped. This is due to the fact, that the header then contains a
variable length element, with the length of the element not given in the
header. Instead, the length is given in the client/server hello message
of the opposite side of the connection (which we might have missed).
Furthermore, parsing is not of a high importance, since we are not
passing the connection ID, or any of the other parsed values of the
unified header into scriptland.

Implement from_json bif
Minor updates during merge: Moved ValFromJSON into zeek::detail for the
time being, removed gotos, normalized some error messages to lower case,
minimal test extension and added a raw reader input framework test reading
"json lines" as a demo, adding notes about the implicit type
conversions.
The NTP mode provides us with the identity of the endpoints. For the
simple CLIENT / SERVER modes, flip the connection if we detect
orig/resp disagreeing with what the message says. This mainly
results in the history getting a ^ and the ntp.log / conn.log
showing the corrected endpoints.
Closes#2998.
* origin/topic/awelzel/smb2-state-handling:
NEWS: Add entry about SMB::max_pending_messages and state discarding
scripts/smb2-main: Reset script-level state upon smb2_discarded_messages_state()
smb2: Limit per-connection read/ioctl/tree state
DTLSv1.3 changes the DTLS record format, introducing a completely new
header - which is a first for DTLS.
We don't currently completely parse this header, as this requires a bit
more statekeeping. This will be added in a future revision. This also
also has little practical implications.
Currently, if a TLS/DTLS analyzer fails with a protocol violation, we
will still try to remove the analyzer later, which results in the
following error message:
error: connection does not have analyzer specified to disable
Now, instead we don't try removing the analyzer anymore, after a
violation occurred.
This is similar to what the external corelight/zeek-smb-clear-state script
does, but leverages the smb2_discarded_messages_state() event instead of
regularly checking on the state of SMB connections.
The pcap was created using the dperson/samba container image and mounting
a share with Linux's CIFS filesystem, then copying the content of a
directory with 100 files. The test uses a BPF filter to imitate mostly
"half-duplex" traffic.

Add irc_dcc_send_ack event and fix missing fields
I've moved IRC_Data back into the zeek::analyzer::file namespace, but
we did move the declaration from protocol/file/File.h to protocol/irc/IRC.h.
But, if someone actually customized IRC_Data and didn't include protocol/irc/IRC.h
for other reasons, I'll be surprised (and also just suggest to update the include).
publish_hrw() and publish_rr() are excluded from type checking due to their
variadic nature. Passing a wrong type for the pool argument previously triggered
an abort, now the result is runtime errors. This isn't great, but it's
better than crashing Zeek.
Closes#2935
The known_log_certs table is populated asynchronously via broker after a
Broker::peer_added. It may take a variable amount of time depending on where
we run this test and it has been observed flaky specifically for the
arm_debian11 task. Instead of racing, give worker-2 3 seconds for receiving
the expected table content before continuing.
Fixes#2885
This new table provides a mechanism to add environment variables to the
postprocessor execution. Use case is from ZeekControl to inject a suffix
to be used when running with multiple logger.
While working on a rotation format function, ran into Zeek crashing
when not returning a value from it, fix and recover the same way as
for scripting errors.
